Creates all the possibilities and then add them up.
union_probability Assumes independence between the probabilities to
calculate the final size.
Usage
union_probability(p)
length_probability(p, size)
Arguments
- p
Numeric vector of probabilities.
- size
Integer value of the size of the selected values.
Value
A numeric value of the probability of the given size.
Examples
length_probability(c(0.5, 0.75), 2)
#> [1] 0.375
length_probability(c(0.5, 0.75, 0.66), 1)
#> [1] 0.2525
length_probability(c(0.5, 0.1, 0.3, 0.5, 0.25, 0.23), 2)
#> [1] 0.3485187
union_probability(c(0.5, 0.1, 0.3))
#> [1] 0.685
